Application filed March 12, 1900. Serial No. 8.351. (No model.)

To all whom it may concern.-

Be it known that 1, WILLIAM HAMILTON MOGOLDRIOK, a citizen of the UnitedStates, and a resident of San Antonio, in the county of Bexar and Stateof Texas, have invented a new and Improved Gas-Machine, of which thefollowing is a full,clear,and exact description.

This invention relates to improvements in machines for generatingacetylene-gas; and the object is to provide a gas-machine ot' simple andcomparatively inexpensive construction, in which the gas is thoroughlywashed before entering the servicepipe and in which the water-su pplytothe generator is controlled by the gas-pressure and the carbid kept atall times cooled by surrounding water,

I will describe a gas-machine embodying my invention, and then point outthe novel features in the appended claims.

Reference is to be had to the accompanying drawings, forming a part ofthis specification, in which similar characters of reference indicatecorresponding parts in all the figures.

Figure 1 is a perspective view of a gasmachine embodying my invention.Fig. 2 is a plan view and partial section on the line 2 2 of Fig. 3, andFig. 3 is a section on the line 3 3 of Fig. 2.

The gasometer comprises a fixed tank 4, in which a hell 5 is movable,and the bell is guided in its upward and downward movements by rods 6,extended upward from the tank 4, and with which grooved rollers 7 on thetop of the bell engage. Arranged on the top of the bell is agenerator-dome consisting of an outer wall 8 and an inner wall 9, thespace between these walls being designed to receive water to serve as aseal for a cover 10, having a wall 11 extended down into the water, asplainly indicated in Fig. 3. As a further means for providing agas'tight con nection between the cover and the gen eratordome I mayemploya gasket 12, of rubber or the like, arranged between the cover andthe inner wall of the generator-dome.

The generator consists of a cylinder 13 extended upward from the bottomof the tank 4and arranged within a jacket 14, which depends froin thetop of the bell 5 and has its open upper end extended upward slightlyabove the bottom portion of the generatordome wall 9, thus forming awater-space between said jacket and the wall 9, and through this waterthe generated gas is designed to pass, so as to be thoroughly washed.

An open work carbid -basket 15 is supported in the cylinder 18. As hereshown, the basket has arms 16, designed to engage over the upper end ofthe jacket 14, and to these arms 16 a suitable handle 17 is attached, sothat the basket may be readily removed or inserted after removing thecover 10.

A pipe 18 provides communication between the interior ofthe wall 9 ofthe generator-dome and the space in the bell 5 above the water containedtherein. From this space in the bell the gas passes through the service-pipe 19, which has its upper end within the bell extended above thewater-level. A drip-pipe 20 leads from the lower portion of theservice-pipe 19 into the water contained in a bucket or tank 21. Thispipe is designed to carry off the moisture escaping from the gas passingthrough the service-pipe. A safety or blow-off pipe 22 extends upwardinto the bell and into a jacket 23, carried by said bell.

Arranged in the service-pipe is a shell 19, design ed to receive cottonor similar material for cleaning the gas passing therethrough. Thecotton may be replaced with new cotton, as required, upon removing thescrew-plug at the end of the shell and after closing the valves at theends.

Under excessive pressure or excessive amount of gas in the bell it willbe raised until an opening 24 reaches a point above the level of thewater in the bell. Then the surplus gas may escape through said opening24 and pass out through the pipe 22 and through a communicating pipe 25,leading therefrom to the outer atmosphere. This pipe 25 also has adrain-pipe 26 extended into the water in the tub 21. The pipe 18 isprovided with a valve 27 and also with a vent 28, so that when the valveis closed to cut off the passage of gas from the generator to the bellthe said vent will be opened to allow waste gas to blow off. If desired,the vent may be connected to the top of the jacket 23.

Attached to one side of the tank 4, near its top, is a trough 29, whichcommunicates through an opening 30 with the interior of the tank 4. Fromthe trough 29 a pipe 31, having a valve 31, leads to a pipe 32, vhichcommunicates with the interior of the generatorcylinder 13. The bottomof the cylinder is made funnel-shaped, as plainly indicated in Fig, 3,so that Waste products falling from claim as new and desire to secure byLetters the basket 15 will readily pass into the pipe 32, from whichthey may be Withdrawn with the water after opening a valve 33 in thepipe 32. By this means the generator may be thoroughly and quicklycleaned.

In operation, after placing water in the space between the walls 8 and 9of the generator-dome, and also placing water in the tank 4, the saidwater extending upward into the bell and into the space between thecylinder 13 and the jacket 14:, the basket containing the carbid is tobe placed in the generator, after which the cover 10 is to be placed inposition and securely locked. As a locking means I have here indicatedpins extended inward and downward from the top of the wall 8 and adaptedto engage in bayonet slots or notches formed in the top wall of thegenerator-dome. Water poured into the trough 29 will pass through thepipe 31 into the generator-cylinder 13 to a level slightly above thebottom of the basket suspended in the cylinder. After thus placing theparts in operative position the subsequent action is practicallyautomaticthat is, in its supply of water to the generator-because thepressure of gas in the bell will force the water downward in the bell,causing it to rise at the outer surface of the bell and pass through theopening 30 into the trough 29, and thence through the pipe 31 to thegenerator-cylinder 13.

' It is obvious that a machine constructed as shown and described has noparts, such as valves, liable to get out of order, and therefore afterthe first cost there will be no expense to keep the machine in properworking condition, and; further, in view of the great amount of waterseal employed-there can be no possible escape of gas into a room,excepting consumed at the burners.

Having thus described my invention, I

Patentv 1. A gas-machine, comprising a tank, a bell mounted to movevertically therein, a generator-dome on the bell and consisting of innerand outer walls spaced apart to provide a water-space, a-cover for thedome, a pipe leading from the interior of the dome through theWater-space and to the interior of the bell above the water-levelthereof, a valve in said pipe, a vent connecting with said pipe andmovable in the tank, a pipe leading from the generator to the bell, adrip-pipe leading from the service-pipe into a tub adapted to containliquid, a blow-off pipe extended upward in the tank, a pipe carried bythebell and surrounding said blow-oft pipe, a drip-pipe leading from theblow-01f pipe into said'tub, and

a blow-otfpipe leading from the said pipe car-- ried by the bellto apipe connection between -the generator and the bell, substantially asspecified.

In testimony whereof I have signed my two subscribing witnesses.
